using the WITH Clause
The sql statement isSelect ename, job
from emp, dept
where emp.deptno = dep.deptno
and emp.deptno = 10
Union
Select ename, job
from emp, dept
where emp.deptno = dep.deptno
and emp.deptno = 20
the statement above using the WITH Clause
WITH dept10 AS
(select ename, job, hiredate, sal, comm, dname, emp.deptno
from emp, dept
where emp.deptno = dept.deptno
and emp.deptno = 10)
dept20 AS
(select ename, job, hiredate, sal, comm, dname, emp.deptno
from emp, dept
where emp.deptno = dept.deptno
and emp.deptno = 20)
SELECT *.
OF dept10
UNION
SELECT *.
OF dept20
Correct me if I'm wrong...
Thank you

the Question is how u would provide the statement above by using the Clause
The answer is that the question is meaningless. You will not use a WITH clause for this work.
Because you must use a WITH clause to get the same results as the first query, I think the best way would be:
WITH unnecessary_sub_query AS
(
select DISTINCT
ename, job
-- , hiredate, sal, comm, dname,emp.deptno -- these columns are not in the original query
from emp
, dept
where emp.deptno = dept.deptno
and emp.deptno IN (10, 20)
)
SELECT *
FROM unnecessary_sub_query;
is this correct using Clause WITH or correct me
No, it's not ok to make queries more complex or slow they need to do.
In addition to the extra columns, it seems that the second query that you posted (the one who has a WITH clause) produces the same results as the first request.

I have trouble understanding the following query:
SELECT cust_city, COUNT (cust_last_name)
Customers
WHERE cust_credit_limit > 1000
GROUP BY cust_city
HAVING AVG (cust_credit_limit) BETWEEN 5000 AND 6000
According to my preparation for the review, it will work successfully without errors, although I don't understand why.
The AVG (cust_credit_limit) should also be included in with the rest of the fields to make it work correctly?
It would be greatly appreciated if someone could explain it to me better.
Thank you

No - the AVG function doesn't have to be in the select list. Explain why you think it should be.
How would it make a difference if you added to the SELECTION list and ignored, then?
When you have questions DOC the first thing you need to do is RTFM. See the HAVING clause in the RFSO of the SQL language
http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_10002.htm
>
HAVING clause
Use of the
HAVINGclause to restrict groups of returns of the lines to these groups for which the specifiedconditionisTRUE.>
As the doc t says
He HAVING condition applies to the 'groups '.
If you use the HR. EMPLOYEES table you can see the effect of the HAVING clause. This query is similar to yours but with none HAVING clause, and the AVG (salary) added to the selection list to see which groups will have
>
Select department_id, count (last_name), avg (salary)
employees
where salary > 500
Group by department_id- DEPARTMENT_ID, COUNT (LAST_NAME), AVG (SALARY)
- 10,1,4400
- 20,2,9500
- 30,6,4150
- 40,1,6500

>
Note that 60 is the ONLY group with AVG (salary) between 5000 and 6000
Now, try the query using the HAVING clause
>
Select department_id, count (last_name)
employees
where salary > 500
Group by department_id
having avg (salary) between 5000 and 6000
DEPARTMENT_ID, COUNT (LAST_NAME)

Only group 60 has been selected - the HAVING condition has been applied to the first query GROUPS, not the lines.

Cannot use the command clause contained in the posting online of a cursor
Dear people,
I use Oracle 10 g with forms 6i. I had a requirement where I gotto choose the latest ten records and view the sorting in the opposite order.say for ex.
But my problem is all the time that I came to know that we cannot use the order by clause in the view of a cursor line in forms 6i. Think it's one of the limitations of forms 6i.so u can suggest me what I can do to get the expected results? do we not have any alternative?Cursor C is select * from (select ename,sal from emp order by sal desc) where rownum<=10;
Thanking you,
Concerning
Vids
Published by: vidusnat on July 4, 2012 03:38Hello
Please specify!
Forms 6i must be with an older version of SQL and PL/SQL (8.x).To keep it simple create a VIEW in the comics with your as its source and the use of the VIEW in the form. As you noted, it works in 10g and exploit it.
See you soon,.

DML with values returned of dml another inside the WITH clause
Hello community, I want to use the ELECTION of an insert or update values to other insertion within a single transaction without staging of values returned. Here's what I mean. In some other dbs, I can do it like this
WITH moved_rows AS)
DELETE FROM products
"WHERE purchased_date > = ' 2010-10-01' AND purchased_date < ' 2010-11-01"
RETURN *.
)
INSERT INTO products_log
SELECT product_id, product_date, sysdate, user moved_rows;
I know the return value must be assigned to a local variable before they can be used within other dml, but I'm curious to know if the approach described above is supported in Oracle. Note that outside dml returns all columns (*) of the table products and then I took and chose the values I want to be inserted in the log table.

Non - "approach above" don't is NOT supported in Oracle.
For operations from multiple tables, you must use SET of treatment to prevent other sessions modify data during your transaction.

Huh? How can you put a SELECT statement in a procedure? you return a cursor reference?
You create VIEWS. You have three sections. Give an opinion on each of them. Test them with SQL Developer (or SQL * more)
Build from there.
In fact, it looks like you are trying to compare two tables"and return a DIFF
THINKING IN SETS
Use the WITH clause to build a 'virtual' table for EARLIER_NOTICE and a 'virtual' table for LATER_NOTICE.
Use FULL OUTER JOIN to compare the two.
THE FORMAT OF THE EXAMPLE:
select * from ( with w as ( .... ) ,table_A as ( -- build the Virtual Table for EARLIER_NOTICE SELECT * FROM V_URMT_COMPARE_NUCLIDE_DATA A1 join W on (A1.urmt_btrs_pk, W.urmt_btrs_pk and A1.earlier_notcie_id=W.earlier_notice_id) -- old code -- WHERE -- 1 = 1-- why??? -- AND A.URMT_BTRS_PK = (SELECT URMT_BTRS_PK FROM W) --TO_NUMBER(:P202_URMT_BTRS_PK) -- AND A.URMT_NOTICES_ID = (SELECT EARLIER_NOTICE_ID FROM W) --TO_NUMBER(:P202_COMPARE_EARLER_NOTICE_ID) ,table_b as ( -- build the Virtual Table for the LATER_NOTICE select * from V_URMT_COMPARE_NUCLIDE_DATA B1 join W on (b1.urmt_btrs_pk = W.urmt_btrs_pk and b1.urmt_notice_id=W.later_notice_id) ) --/*** NOW - WE COMPARE THE TWO ***/ select CASE when A.urmt_btrs_pk is null then 'ADDED' when B.urmt_btrs_pk is null then 'DELETED' else 'possibily updated' end CHANGES_MADE , A.* , B.* FROM TABLE_A A FULL OUTER JOIN B ON ( A.URMT_BTRS_PK = B.URMT_BTRS_PK AND A.NUCLIDE = B.NUCLIDE ) -
Formula using the following string...
Hi all
Given a set of strings that can is be parsed (see format below), possible to do a TWG
a set of such strings - i.e. the chain may have the form (from
another thread (pricing using the string formula)) the chain is a bulk
dicount "record" for a product - product code not included for now.
I want to use SQL exclusively, but am open to suggestions - examples
using WITH are especially welcome - has spent time last night, a truck load
rising WITH (of no use, it must be added ;))
_100 (20) 90 (50) 80_ String format
See the code below*-20 first purchased items cost 100,.
the cost of the next 50 90 and all the foregoing is 80/unit.
What I would like is to be able to build a 'table' that I can join real Oracle
tables - imagine these "records" of the chain are coming thick and fast and for reasons x, y
or z, prices can be written to a permanent table. A product code must be
included, but I think fundamental analysis once did, adding such a code should not
be a problem.
So, if I have a set of these strings, how build a TWG?
If it is the right approach.
Any ideas, references, URL - be it, much appreciated.
What would be really cool is if the code could take a product with an arbitrary
number of discounts - 2, some 3 (that is, for example), 4... & c...
TIA

CREATE TABLE table_x ( id NUMBER (6) PRIMARY KEY , txt VARCHAR2 (30) ) ; INSERT INTO table_x (id, txt) VALUES (0, NULL); INSERT INTO table_x (id, txt) VALUES (1, '75'); INSERT INTO table_x (id, txt) VALUES (2, '100(10)80'); INSERT INTO table_x (id, txt) VALUES (3, '100(20)90(50)80'); COMMIT;In addition, to say what version of Oracle you are using. The query below work Oracle 10.1 and higher:
WITH cntr AS ( SELECT LEVEL AS n FROM dual CONNECT BY LEVEL <= 5 -- worst case ) , rates AS ( SELECT x.id , x.txt , c.n , TO_NUMBER ( REGEXP_SUBSTR ( '0)' || x.txt , '[^()]+' , 1 , (2 * c.n) - 1 ) ) AS start_qty , TO_NUMBER ( REGEXP_SUBSTR ( x.txt , '[^()]+' , 1 , (2 * c.n) - 1 ) ) AS rate FROM table_x x JOIN cntr c ON c.n <= LENGTH (txt) + 1 - LENGTH (REPLACE (txt, '(')) ) SELECT * FROM rates ORDER BY id , n ;Output:
` ID TXT N START_QTY RATE ---------- ------------------------------ ---------- ---------- ---------- 1 75 1 0 75 2 100(10)80 1 0 100 2 100(10)80 2 10 80 3 100(20)90(50)80 1 0 100 3 100(20)90(50)80 2 20 90 3 100(20)90(50)80 3 50 80If you use the WITH clauses above in any question, you can use rates in table form in the following parts of the query.
This assumes you know an upper limit for the number of items in the string. I took 5 different rates above, but you can easily change that to any fixed number. You can also derive the exact number of data themselves. I'll leave that as an exercise.
You can use the analytical function of LEAD to add another column, end_qty, rates.

It also means that txt is well-formed. A space before or after the parentheses is probably correct, but in additional brackets, letters, several decimal places or sign in the same 'number' and things like that will cause all errors.START_QTY is a misleading name; I should have used something like LOW_QTY or PREV_QTY. In the example above, the row with id = 3 and start_qty = 20 applies in reality to the amount above 20, i.e. 21 to 50 inclusively (since 50 is START_QTY for this id).

Insert using the table with the clause and select?
Hello gurus,
Can I insert in a table by making use of clause and select?
something similar to this...
Thank you very much!!!insert into test_table (with abc as (select * from emp_tble where dept_no = 10 ) select * from abc; ); if not i would i do by making use of with clause & select ... any example would be great !!Brackets are disturbing only:
SQL> insert into test_table (with t as (select * from emp) select * from t) / Error at line 12 ORA-32034: unsupported use of WITH clause SQL> insert into test_table with t as (select * from emp) select * from t / 14 rows created. -
PL/SQL parameter in fusion by using the clause
Hi all
I need to create a procedure where I use the Merge clause. However, by using the condition, I have to put value user_define (V_LOCALE_CD). This value checks table of locale and then to make a match with table of flex_labels_test.
There is no specific requirement and I don't have the test data.
My only question how do I use user set the value using the condition. Here is the procedure I created as follows.
create or replace the PROCEDURE UPSERT_FLEX_LABEL_3 (V_LOCALE_CD IN VARCHAR2,
V_VALUE IN VARCHAR2,
V_FIELDVALUE IN VARCHAR2,
V_FIELDNAME IN VARCHAR2,
V_TABLENAME IN VARCHAR2,
N_FLEX_TYPE NUMBER,
V_COLOR IN VARCHAR2 DEFAULT NULL,
N_IMAGE_LIBRARY_ID IN THE NUMBER DEFAULT NULL,
N_HIERARCHY_ID IN DEFAULT NUMBER 5237260000000000001,
N_IS_INHERITED IN THE DEFAULT NUMBER 1)
AS
L_COUNT NUMBER;
NUMBER OF N_LOCALE_ID;
NUMBER OF NN_HIERARCHY_ID: = 5237260000000000001;
NUMBER OF NN_IS_INHERITED: = 1;
NUMBER OF INSERTCOUNT;
UPDATECOUNT NUMBER;
NUMBER OF ERR_CODE;
ERR_MSG VARCHAR2 (100);
BEGIN
-SELECT ID IN N_LOCALE_ID OF PLACES WHERE LOCALE_CD = V_LOCALE_CD;
/ * IT WILL CHECK DUPLICATES, IF THEY ARE PRESENT, THEN IT WILL UPDATE RECORD ELSE IT WILL INSERT A NEW RECORD * /.
BEGIN
Merge into fl flex_labels_test
using (select locale id where locale_cd = V_LOCALE_CD) L
on (l.id = fl.locale_id)
When matched then
GAME UPDATE
HIERARCHY_ID = NVL (N_HIERARCHY_ID, NN_HIERARCHY_ID),
IS_INHERITED = NVL (N_IS_INHERITED, NN_IS_INHERITED),
FLEX_TYPE = N_FLEX_TYPE,
VALUE = V_VALUE,
IMAGE_LIBRARY_ID = N_IMAGE_LIBRARY_ID,
COLOR = V_COLOR
WHERE TABLENAME = V_TABLENAME
AND FIELDNAME = V_FIELDNAME
AND FIELDVALUE = V_FIELDVALUE
When not matched then
INSERT (HIERARCHY_ID, ID_PARAMETRES_REGIONAUX, IS_INHERITED, FLEX_TYPE, TABLENAME, FIELDNAME, FIELDVALUE, VALUE, IMAGE_LIBRARY_ID, COLOR)
VALUES (NVL (N_HIERARCHY_ID, NN_HIERARCHY_ID), N_LOCALE_ID, NVL (N_IS_INHERITED, NN_IS_INHERITED), N_FLEX_TYPE, V_TABLENAME, V_FIELDNAME, V_FIELDVALUE, V_VALUE, N_IMAGE_LIBRARY_ID, V_COLOR);
UPDATECOUNT: = NUMBER OF ROWS SQL %;
EXCEPTION
WHILE OTHERS THEN
ERR_CODE: = SQLCODE;
ERR_MSG: = SUBSTR (SQLERRM, 1, 200);
DBMS_OUTPUT. PUT_LINE ("ERRORS" |) ERR_CODE | ' AND ' | ERR_MSG);
END;
COMMIT;
DBMS_OUTPUT. PUT_LINE ('RECORD INSERTCOUNT =' |) NVL(INSERTCOUNT,0));
DBMS_OUTPUT. PUT_LINE (' UPDATECOUNT RECORD ='|) NVL(UPDATECOUNT,0));
EXCEPTION
WHEN NO_DATA_FOUND THEN
RAISE_APPLICATION_ERROR (-20001, "ID NOT FOUND REGIONAL SETTINGS");
END;
I guess that's what I was looking for. Thank you guys for your efforts.

Using XQuery with PL/SQL, link the Variable
I am only able to find an example of use of xquery with pl/sql.
[http://www.comp.dit.ie/btierney/oracle11gdoc/appdev.111/b28369/xdb_xquery.htm#CBAEEJDE]
Why is what they show only using bind variables? It's the only way it should be used, it provides a performance gain more simply by using the crossing clause and a passing beam a PL/SQL variable? I'm looking to implement a solution for my company using Xquery in PL/SQL. I am concerned that these procedures will be called during a flow of the user interface and performance it must be as soon as possible.A PL/SQL variable, column, or the output of another operation would be all be equivalent to a connection variable that PL/SQL compilation is concerned. Which would be bad practice would be to build in XQuery with the predicate hardcoded in the XQuery operation whenever the XQuery query has been run.

Not able to connect after changing the password using the VALUES ALTER clause
Hello
John explained earlier the clause VALUES below thread.
Status expired
I created a new account named SURI, and tried to use the password of the user account from the HR by using the VALUES clause. I was able to change the password but not able to connect SURI with HR password.
Please see below for details. And the SQL statements that I have tried.

SuriIts because you have used a different username.
Oracle produces a hash based on the user name and the password, not only the password.Therefore, you can not use the hashed password of a user to log on to the account of another user.
You need to get the password hashed Suri and then connect you to suri by using the password hashed Suri (using the identified by the syntax of values)

My doubt is that I use EMP as with the name of clause.
In the condition when I select of the EMP.
It is guaranteed that extracts data from request formed in the with clause, because I have a table named EMP in my diagram.
Thank you

Yes, if the emp is an alias and emp is also a real table, and both have a scope, then Oracle assumes you mean the alias. To avoid confusion and errors, do not use the actual table as alias names.
It goes same for columns and column aliases.
In PL/SQL, the same type of confusion can arise between the variables and the column names. When there is a choice, Oracle assumes you are talking about the variable.

The error has actually nothing to do with the WITH clause.
Join conditions (i.e. the conditions following the keyword WE) must be expressions that are evaluated to TRUE or FALSE. The join condition, you have validated, however
(R.ITERATION + 1) + B.NUM
corresponding to a NUMBER. The following would be a valid join condition:
(R.ITERATION + 1) = B.NUM
but I don't know if it of what you wanted or not.
